Etkinliklerin zamanlaması
HVAC durumundaki bir değişikliğe ilişkin etkinliğin, termostat modu değişikliğine ilişkin etkinliklerle aynı anda teslim edilmeyebileceğini unutmayın.
Örneğin, HVAC sistemini korumak için bazen termostatın ısıtma veya soğutma moduna başlamasında gecikme yaşanır. Bu senaryoda, termostat modunun değiştirilmesi başlangıçta yalnızca ThermostatMode ve ThermostatTemperatureSetpoint özellik değişiklikleri için etkinlik gönderebilir. ThermostatHvac özellik değişikliği ise sistem gerçekten açıldıktan sonra ayrı bir etkinlik olarak gönderilir. HVAC sistemi açılırken herhangi bir gecikme yaşanmadıysa üç etkinlik de aynı anda gönderilir.
